If you see the red alert sign in summer, you know the air quality in metropolitan Denver and the Front Range region is poor.

24-hour ozone advisories are issued when air quality can be harmful to all of us, especially the young and elderly, those with respiratory illnesses and who spend a lot of time outdoors.

Once air quality has returned to normal levels, the region will return to a non-alert status.

Get Involved with Simple Steps. Better Air.

Our stakeholders are vital to the Simple Steps. Better Air. program. The Environmental Protection Agency continues to tighten ozone standards so there is a great need for regional collaboration to identify new strategies that would bring our region into compliance. If your organization or program operates in Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas, Jefferson, Larimer or Weld counties and would like to get involved, call the RAQC Communications office at 303.629.5450 ext. 220 or visit raqc.org.
